Off-road vehicles have strong off-road capabilities, good passability, strong load-carrying capabilities, and diverse uses, which pose higher requirements for various performances. In the harsh environment of wilderness exploration, the whole vehicle has a larger amount of shaking, and the fuel tank makes noise, affecting the driving experience of customers. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an automotive fuel tank that can reduce noise and improve the driving experience of customers.

[0004] The utility model provides an automotive fuel tank, which includes a fuel tank body, a fuel pump, and several anti-surge plates. The fuel tank body is used for storing fuel. A fuel pump mounting hole is formed on the fuel tank body, and a circular first chuck is arranged around the fuel pump mounting hole on the fuel tank body. A circular second chuck is arranged on the fuel pump. The fuel pump can be inserted into the fuel pump mounting hole, and the fuel pump is fixed to the fuel tank body by clamping the second chuck with the first chuck. Several anti-surge plates are arranged inside the fuel tank body to restrict the free flow of fuel by changing the flow boundary conditions of the fuel.

[0005] For the automotive fuel tank provided by the utility model, the fuel pump is fixed to the fuel tank body by clamping the second chuck with the first chuck, which can effectively prevent the attenuation of the assembly torque and avoid the noise generated by the shaking of the fuel pump. The automotive fuel tank is also provided with several anti-surge plates to restrict the free flow of fuel by changing the flow boundary conditions of the fuel, and block a part of the fuel from hitting the inner wall of the fuel tank body when the fuel tank body shakes, further reducing noise and improving the driving experience of customers.

[0006] In another illustrative embodiment of the automotive fuel tank, the automotive fuel tank further includes several fuel tank straps. Each fuel tank strap is in a long strip shape. A part of each fuel tank strap is wound around the fuel tank body, and both ends of each fuel tank strap can be fixed to the vehicle frame to fix the fuel tank body to the vehicle frame.

[0007] In yet another illustrative embodiment of the automotive fuel tank, several strap grooves corresponding to the shape of the fuel tank straps are recessed on the outer surface of the fuel tank body, and each fuel tank strap is embedded in the strap groove correspondingly. Thereby, the installation stability of the fuel tank body is improved.

[0008] In another schematic embodiment of the vehicle fuel tank, the vehicle fuel tank further includes several fuel tank cushion bands, each of which can be deformed under an external force. The several fuel tank cushion bands are arranged between several fuel tank pulling bands and the fuel tank body to absorb the kinetic energy and noise between the several fuel tank pulling bands and the fuel tank body.

[0009] In yet another schematic embodiment of the vehicle fuel tank, several uniformly arranged fuel passing holes are formed on each anti-sloshing plate. Thereby, the fluidity of the fuel is improved.

[0010] In another schematic embodiment of the vehicle fuel tank, the first chuck has a mounting surface on which several fixing parts are formed. The several fixing parts are uniformly arranged around the axis of the first chuck, and each fixing part has a clamping part extending radially inward or outward along the first chuck. Several first through holes are formed on the second chuck, and the positions of the several first through holes correspond to those of the several fixing parts. The several fixing parts can pass through the several first through holes one by one to make the second chuck fit the mounting surface. Several second through holes are also formed on the second chuck, and the second through holes are in one-to-one communication with the first through holes. When the second chuck fits the mounting surface, the second chuck can rotate relative to the first chuck around the axis of the first chuck, so that each fixing part slides from the first through hole into the second through hole. At the same time, each clamping part and the mounting surface can clamp two end faces of the second chuck to realize the clamping connection between the second chuck and the first chuck.

[0011] In another schematic embodiment of the vehicle fuel tank, a positioning groove is formed on each clamping part, and several positioning parts protrude from the end face of the second chuck facing away from the mounting surface. During the process of each fixing part sliding from the first through hole into the second through hole, the several positioning parts can be embedded into the positioning groove one by one to limit the rotation of the second chuck relative to the first chuck. Thereby, the loosening between the second chuck and the first chuck is avoided, and the stability after assembly is improved. Description of the Drawings

[0038] Figure 1 Schematic structural diagram of a schematic implementation manner of an automotive fuel tank. Figure 2 Cross-sectional view of an automotive fuel tank. Refer to Figure 1 and Figure 2 , the automotive fuel tank includes a fuel tank body 10, a fuel pump 20, and several anti-surge plates 30 ( Figure 2Only one of them is shown.

[0039] Figure 3 It is a schematic exploded view of an automotive fuel tank. Refer to Figure 1 and Figure 3 , the fuel tank body 10 is used to store fuel. A fuel pump mounting hole 12 is formed on the fuel tank body 10, and an annular first chuck 14 is arranged around the fuel pump mounting hole 12 on the fuel tank body 10. An annular second chuck 22 is arranged on the fuel pump 20. The fuel pump 20 can be inserted into the fuel pump mounting hole 12, and the fuel pump 20 is fixed to the fuel tank body 10 by means of the engagement of the second chuck 22 and the first chuck 14.

[0040] Refer to Figure 2 , several anti-sloshing plates 30 are evenly arranged in the fuel tank body 10 according to the shape of the fuel tank body 10 to limit the free flow of fuel by changing the flow boundary conditions of the fuel. When the fuel tank body 10 shakes, several anti-sloshing plates 30 can block a part of the fuel from hitting the inner wall of the fuel tank body 10. Several evenly arranged fuel through holes 32 are formed on each anti-sloshing plate 30 to improve the fluidity of the fuel.

[0041] For the automotive fuel tank provided by the present utility model, the fuel pump 20 is fixed to the fuel tank body 10 by means of the engagement of the second chuck 22 and the first chuck 14, which can effectively prevent the attenuation of the assembly torque and avoid the noise generated by the shaking of the fuel pump 20. The automotive fuel tank is also provided with several anti-sloshing plates 30 to limit the free flow of fuel by changing the flow boundary conditions of the fuel, block a part of the fuel from hitting the inner wall of the fuel tank body 10 when the fuel tank body 10 shakes, further reduce the noise, and improve the driving experience of customers.

[0042] Figure 4 and Figure 5 are schematic diagrams of a working state of the first chuck and the second chuck. Refer to Figure 4 and Figure 5 , in the illustrative embodiment, the first chuck 14 has a mounting surface 142, and several fixing parts 144 are formed on the mounting surface 142 ( Figure 4 and Figure 5 only one of them is labeled), several fixing parts 144 are evenly arranged around the axis of the first chuck 14, and each fixing part 144 has a clamping part 146 extending radially inward or outward along the first chuck 14.

[0043] Several first through holes 222 are formed on the second chuck 22 ( Figure 4 and Figure 5(only one of them is marked), the positions of several first through-holes 222 correspond to those of several fixing parts 144. The several fixing parts 144 can pass through the several first through-holes 222 one by one to make the second chuck 22 fit the mounting surface 142. Several second through-holes 224 are also formed on the second chuck 22 ( Figure 4 and Figure 5 (only one of them is marked). The second through-holes 224 communicate with the first through-holes 222 one by one. When the second chuck 22 fits the mounting surface 142, the second chuck 22 can rotate relative to the first chuck 14 around the axis of the first chuck 14, so that each fixing part 144 slides from the first through-hole 222 into the second through-hole 224. At the same time, each clamping part 146 and the mounting surface 142 can clamp two end faces of the second chuck 22 to realize the clamping connection between the second chuck 22 and the first chuck 14.

[0044] Referring to Figure 4 and Figure 5 , in the illustrative embodiment, a positioning groove 147 is formed on each clamping part 146, and several positioning parts 226 ( Figure 4 and Figure 5 (only one of them is marked) protrude from the end face of the second chuck 22 facing away from the mounting surface 142. During the process that each fixing part 144 slides from the first through-hole 222 into the second through-hole 224, the clamping part 146 will produce slight deformation until several positioning parts 226 can be embedded into the positioning groove 147 one by one to limit the rotation of the second chuck 22 relative to the first chuck 14. This avoids loosening between the second chuck 22 and the first chuck 14 and improves the stability after assembly.

[0045] In the illustrative embodiment, referring to Figure 1 and Figure 2 , the automotive fuel tank further includes several fuel tank straps 40. Each fuel tank strap 40 is in a long strip shape. A part of each fuel tank strap 40 is wound around the fuel tank body 10, and both ends of each fuel tank strap 40 can be fixed to the vehicle frame to fix the fuel tank body 10 to the vehicle frame.

[0046] In the illustrative embodiment, referring to Figure 2 , several strap grooves 16 corresponding to the shape of the fuel tank straps 40 are recessed on the outer surface of the fuel tank body 10. Each fuel tank strap 40 is embedded into the strap groove 16 one by one. This prevents the fuel tank body 10 from sliding relative to the fuel tank straps 40 and improves the stability of the installation of the fuel tank body 10.

[0047] In the illustrative embodiment, referring to Figure 2, the vehicle fuel tank further includes several fuel tank cushion belts 50. Each fuel tank cushion belt 50 can be deformed under an external force. The several fuel tank cushion belts 50 are arranged between the several fuel tank tie-down straps 40 and the fuel tank body 10 to absorb the kinetic energy and noise between the several fuel tank tie-down straps 40 and the fuel tank body 10.
